Deep chest pain at 20 weeks

A

I’m 20 weeks pregnant and woke up at 1am with this somewhat intense pain deep in my chest (near my heart, but it’s not heartburn). It’s really hard to describe, but kind of like something really heavy had been sitting on my chest for a long period of time and then was lifted and I’m left with this deep soreness/sharpness.

When I move suddenly, the pain gets worse. It’s been 5 hours and the pain has not subsided at all.

Has anyone else dealt with this or should I be concerned?

I have an OB appointment tomorrow afternoon and will be sure to ask about it regardless.
